What problem does it solve? Build, compile, dependency-resolution, and startup failures block development, and fixing them often tempts quick suppressions (type ignores, fake migrations, silent version bumps) that hide the real cause. This Skill resolves such failures with the smallest honest diff, verified by re-running the actual build command. ## Core Features & Use Cases - Automatic stack detection and routing: Detects the toolchain from project files (package.json, go.mod, Cargo.toml, pubspec.yaml, .csproj, and more) and loads a matching diagnostic reference for 17 stacks including JavaScript/TypeScript, Django/Python, Go, Rust, Java/Spring, Kotlin, Swift, Flutter, .NET, C++, and Ruby. - Structured six-phase loop: Reproduce the exact error, classify it against diagnostic tables, read the affected file, apply one surgical fix at a time, verify by re-running the build, then report. - Anti-suppression reflection gate: Before reporting success, it checks for suppressed errors, widened types, unplanned dependency bumps, and unverified builds, reverting and escalating instead of reporting a false fix. - Use Case: A developer pastes a Gradle "Duplicate class" error or a Django "InconsistentMigrationHistory" traceback; the Skill identifies the error family from the stack-specific table, applies the minimal fix, and confirms the build is green. ## Quick Start Ask the assistant to fix the failing build or compile error in this project and paste the exact error output or stack trace.
